Composite and efficient oil-water-separation filter paper for hydraulic filter

Abstract

The invention discloses composite and efficient oil-water-separation filter paper for a hydraulic filter. The composite and efficient oil-water-separation filter paper is prepared by, by weight, 50-55 parts of 3-5mm alkali-free superfine glass fiber, 55-60 parts of bleached softwood pulp, an appropriate amount of distilled water, 0.8-1 part of anionic polyacrylamide, an appropriate amount of concentrated sulfuric acid with the concentration being 98wt%, 10-12 parts of nano titanium dioxide, 20-25 parts of ferroferric oxide colloidal solution with the solid content being 30%, an appropriate amount of anhydrous ethanol, 60-65 parts of fluoro-silicon emulsion with the solid content being 40wt%, 1-1.2 parts of alkenyl succinic anhydride, 7-8 parts of sisal fiber, 3-4 parts of waste rubber powder, 0.9-1.1 parts of silane coupling agent kh550, 1.5-2 parts of organic silicon emulsion and 2-3 parts of urea. By the scientific and reasonable component proportion, the composite and efficient oil-water-separation filter paper is good in absorbability, good in hydrophobic and oleophylic performance and capable of efficiently separating oil and water. When the filter paper is applied to the hydraulic filter, hydraulic equipment can be well protected.

Description

technical field [0001] The invention relates to the technical field of filter paper, in particular to a composite high-efficiency oil-water separation hydraulic filter filter paper. Background technique [0002] Nowadays, our society is developing rapidly, and most enterprises will choose mechanical operation methods in the construction process. With the continuous improvement of science and technology, in terms of mechanical operation, enterprises have applied the construction method of mechatronics. During the use of machinery, no matter how carefully the operator installs and operates the equipment, it will inevitably cause varying degrees of pollution to the hydraulic oil. The maintenance of hydraulic oil will take a lot of time and money, so hydraulic oil has become a part of the mechanical use process. the most important part of the. During the use of the machine, the hydraulic oil is mainly used to penetrate other parts for operation. Due to the water, gas and dust ...

Problems solved by technology

However, the filter paper used in this article is ordinary filter paper, which does not have good high temperature aging resistance and corrosion resistance, and the filter paper will be damaged under pressure for a long time, resulting in filter failure, which will directly increase the production cost, and should be developed. A filter paper that can be easily replaced, not only can resist a certain pressure, has good strength, can be used in high temperature oil, but also can filter the moisture in the hydraulic oil and the mechanical impurities in the system, etc., at the same time save costs
